Subject: [RESEND v3 24/52] ARM: i.MX: xload-esdhc: Allow custom buffer address, device offset
Date: Thu, 7 Jun 2018 06:00:40 -0700 [thread overview]
Message-ID: <20180607130108.5339-25-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180607130108.5339-1-andrew.smirnov@gmail.com>
Add code to support specifying different buffer address and SD/MMC
device offset to read it from in esdhc_start_image(). This change is
needed to support i.MX8.
NOTE: We intentionnaly "emulate" reading at arbitrary offset in
esdhc_start_image() as opposed to implementing it in
esdhc_read_blocks() in order to avoid having to detect if units of
blocks or bytes should be used to specify offset to CMD18.
